Understanding the Relationship Between Shrinking Cities and Land Prices:Spatial Pattern,Effectiveness,and Policy Implications

Urban shrinkage has emerged as a widespread phenomenon globally and has a significant impact on land,particularly in terms of land use and price.This study focuses on 2851 county-level cities in China in 2005–2018(excluding Hong Kong,Macao,Taiwan,and‘no data’areas in Qinhai-Tibet Plateau)as the fundamental units of analysis.By employing nighttime light(NTL)data to identify shrinking cities,the propensity score matching(PSM)model was used to quantitatively examine the impact of shrinking cities on land prices,and evaluate the magnitude of this influence.The findings demonstrate the following:1)there were 613 shrinking cities in China,with moderate shrinkage being the most prevalent and severe shrinkage being the least.2)Regional disparities are evident in the spatial distribution of shrinking cities,especially in areas with diverse terrain.3)The spatial pattern of land price exhibits a significant correlated to the economic and administrative levels.4)Shrinking cities significantly negatively impact on the overall land price(ATT=–0.1241,P<0.05).However,the extent of the effect varies significantly among different spatial regions.This study contributes novel insights into the investigation of land prices and shrinking cities,ultimately serving as a foundation for government efforts to promote the sustainable development of urban areas.

Relationships between Basic and Silicic Magmatism in Continental Rift Settings:A Petrogeochemical Study of Carboniferous Post-collisional Rift Silicic Volcanics in Tianshan,NW China

Petrogeochemical data are reported for silicic volcanic rocks from the Tianshan Carboniferous rift, with the aim of discussing the petrogenesis of silicic magmas. Incompatible element vs. incompatible element diagrams display smooth positive trends for the Tianshan Carboniferous rift-related volcanic rocks; the isotope ratios of the silicic lavas [^87Sr/^86S（t）=0.699880.70532; eNd（t）=4.76-8.00; ^206pb/^204pb（t）=17.435-18.017; ^207Pb/^204Pb（t）=15.438-15.509; ^208Pb/^204Pb（t） = 37.075-37.723] encompass those of the basic lavas. These data suggest a genetic link between rhyolites and basalts, but are not definitive in establishing whether silicic rocks are related to basalts through fractional crystallization or partial melting. Geochemical modeling of incompatible vs. compatible elements excludes the possibility that silicic melts are generated by the melting of basaltic rocks, and indicates a derivation by fractional crystallization plus moderate assimilation of wall rocks （AFC） starting from intermediate rocks to silicic rocks. Continuous AFC from basalt to rhyolite, with small rates of crustal assimilation, best explains the geochemical data. The presence or absence of bimodal volcanism （the ＂Daly Gap＂） might be related to cooling rates of magma chambers. In central and eastern Tianshan, the crust was thinner and the cooling rates of the magma chamber within the crust were greater. These conditions resulted in a rapid fall in temperature within the magma reservoir and caused a narrow temperature interval over which intermediate melts formed, effectively reducing the volume of the intermediate melts.

On the 2002 U. S. Mid-Term Election Zhang Yanyu and Wang Wenfeng are both assistant research professors at the Division for American Studies in China Institute of Contemporary International Relations

The first mid-term election of the U. S. in the new century took place on November 5, 2002. One third of the senators from the 107th Congress (34 out of 100), all representatives (435), 36 state governors, and numerous local officials and legislators were to be elected or reelected. The resounding victory of the GOP in the congressional elections and the fact that the Democrats only got three more.

China-US Trade Relations:Win-Win Picture Distorted

At present China-U.S.trade relations are in a state of confusion.Although both countries have gained tremendous benefits from the bilateral trade relationship,some Americans have intentionally distorted some basic facts regarding China-U.S.trade relations. Based on an analysis of some official and nonofficial research reports published in the United States,this article holds that the China-U.S.trade imbalance is the symptom of a bigger issue stemming from the contradiction between the United States as the world's sole superpower and China as an emerging power.Economic globalisation came about due to the needs of western developed countries represented by the United States to boost economic development.Only by seizing the opportunities of economic globalisation, has China gained strong economic growth. Such a development is changing the world political,economic,military and cultural landscape that have been shaped since the post-cold-war era,and has to some extent raised doubt or suspicion on the part of the United States and its western allies.This is a manifestation of how unprepared some people in the United States and other western countries are in the face of China's rapid development and rising status.So,their immediate reaction has been to seek protection for themselves,and try their utmost to prevent China's rapid growth from impacting on the international framework and their vested interests.

The Trend of U.S.-China Relations: Is a Conflict Between the United States and China Inevitable?

International relations theory can serve as a guide to understanding national behaviour,especially those that are strained by ideological misunderstandings.Realism basically believes that state behaviour reflects the state’s pursuit of power.Constructivism believes that thought drives behaviour.Therefore,in order to better understand the behaviour between states,this essay suggests that constructivism and realism can interact rather than repel each other,because constructivism can play a complementary role in realism.This combination can promote behavioural understanding between countries without compromising the interests of countries,thereby reducing the possibility of conflict and war.Finally,the ups and downs of Sino-US relations reflect the participation of ideology.In other words,based on this method to analyse the current relationship between China and the United States,it can be predicted that the two countries can basically avoid the war between them.

China-Japan Security Relations and China＇s Countermeasures

Security relations are crucial in China-Japan relations. Since the"nationalization"of the Diaoyu Islands by Japan in 2012, mutual trust between China and Japan has been declining, and bilateral security relations have reached a low point. China-Japan security relations are typified by ongoing dispute over the Diaoyu Islands, lack of mutual trust exacerbated by various actions by Japan, and the delay of China-Japan security dialogues. The evolution of China-Japan security relations derived from the Diaoyu Islands dispute is clearly beyond the scope of the dispute itself, with deep-rooted internal and external factors. In the near future,China-Japan security relations will face more challenges than opportunities. China should take measures, including enhancing mutual trust in politics and security between the two countries, to impose necessary pressure on Japan to change course, to win over neighboring countries so as to avoid pretext for Japan's intervention in regional issues,and to strengthen interpersonal communication and understanding between people of the two countries in order to stabilize security relations.
